ATV Regulator/Rectifiers

ATV Regulator/Rectifier ATVs use several different types of power systems depending on whether they only have an ignition system, they have lights, or they have a full electrical system with a battery.

Most ATV's come with lights and use a stator with a source coil to power the ignition system and a lighting coil or winding to provide power to the lights. Often these lights run in AC power using no battery. The power provided by the stator varies with the engine speed. When the engine is running at idle, the lights tend to dim. Once the throttle is opened, the lights brighten. To prevent the lights from burning out from too much power, an AC regulator is used. Once the voltage reaches a certain point, between 12 and 14 volts, the regulator takes the extra AC power from the power wire and sends it to ground which, in the case of an ATV, is the frame.

ATV Regulator/RectifierATVs with batteries must convert the AC power from the stator into DC. In order to do this, the power coming from the stator must be converted by a regulator/rectifier. The rectifier actually converts the power from AC to DC, while the regulator keeps the power level (voltage) from going above the 13.8 -14.5 volts needed to power a standard 12 volt battery. It is important that the stator provides more power than needed by the ATV so that the battery will stay charged. If the ATV uses more power than the stator can provide, the battery will start to drain. This will typically happen if the voltage drops below 13 volts.

Electronicamotos regulator/rectifiers are designed to be direct replacements to original equipment using stock mounting locations and OEM style connectors. These parts are designed to handle higher power loads than their OEM counterparts.

* It should be noted that when an ATV has been converted from an AC system to a DC power system, a regulator/rectifier is used to replace the stock AC regulator. The AC regulator should be removed. Often the mounting location must change because a regulator/rectifier is larger than an AC regulator. As with any electrical part, it is important to follow the included directions when installing them. When mounting a regulator/rectifier, especially to a bike with upgraded lighting and stators, these parts will get warm and should be allowed cooling airflow.
